Viscous Wall Dampers: 20 Years of Japanese Data, Now in the U.S.
Base isolation works beautifully on mid-rise buildings. On tall, flexible buildings, you need a different tool. Viscous wall dampers have done that job in Japan for two decades, and they are now qualified for U.S. critical facilities. Here is the physics and the first North American installation.
Retrofitting History: Seismic Isolation for Old Buildings
Conventional seismic strengthening tears up the very fabric of a historic building. Isolation does the opposite: it leaves the building above mostly untouched and addresses the earthquake problem underneath. From the 1894 Salt Lake City and County Building to the New Zealand Parliament, here is how it works on buildings you cannot replace.
The Economics of Seismic Isolation: Often Cheaper Than Not
Seismic isolation has a reputation as a premium upgrade. In practice, when it is part of the design from day one, it routinely reduces total project cost. Here is how the foundations, structure, and contents all get smaller, with numbers from real bridges and buildings.
Hospitals That Don't Stop: Seismic Isolation in Critical Care
A hospital that survives an earthquake but cannot operate is, for the people who needed care that morning, the same as a hospital that collapsed. That is why hospital seismic design has shifted from survivability to operability, and why isolation has become the default for new critical care construction in seismic regions.
Inside a Lead Rubber Bearing: The Engineering, Explained
A lead rubber bearing looks like a hockey puck and weighs as much as a small car. Inside is a precise sandwich of natural rubber, laser-cut steel shims, and a lead plug. Here is what each piece does and how DIS builds and tests them.
How Seismic Isolation Actually Works: The Physics, Plainly
Most earthquake-resistant buildings try to be stronger than the shaking. Isolated buildings do the opposite: they let the ground move while the structure stays roughly still. Here is the physics of why that works, with a real case from the 1994 Northridge earthquake.
En qué estamos trabajando.
DIS desarrolla aislamiento tridimensional de baja masa

DIS realiza ensayos a escala real para la NRC
Estructura de tamaño real ensayada en la mesa vibradora más grande del mundo en Kobe: aceleraciones reducidas en más de un factor de 3 para aislamiento de grado nuclear.
Instalado el primer amortiguador de muro viscoso de Norteamérica
Geary Van Ness Medical Center, San Francisco: la primera instalación del DIS VWD en los EE. UU., fabricado y ensayado en Reno, Nevada.
¿Tiene un proyecto donde el tiempo fuera de servicio no es una opción?
Nuestros ingenieros trabajan junto a usted desde el concepto hasta la instalación. Cuando participamos desde la fase de diseño, el costo total del proyecto suele reducirse hasta en un 30%.
